Tech Terms: MRI-Ultrasound Fusion-Guided Biopsy
When entering the world of prostate care, there are going to be many terms used by physicians with which patients may be unfamiliar. In a previous post, we broke down the tech term “multiparametric-MRI (mp-MRI)”. Now we want to help explain another term, MRI-Ultrasound (MRI-US) Fusion-Guided Prostate Biopsy or Fusion Biopsy
The only way to definitively diagnose prostate cancer is with a needle biopsy that is submitted to a pathology laboratory for analysis. The use of advanced diagnostics, such as MRI-US Fusion-Guided Biopsy, takes the process several steps further and is crucial when trying to identify and characterize a prostate cancer tumor, assess the risk, and provide a personalized treatment plan for each patient, says Vituro Health Medical Director Stephen Scionti, M.D.
“There is no excuse, today, to depend solely on the traditional method of using a blind and random needle biopsy to search for a tumor,” Dr. Scionti explains. “If an MRI is performed first, and the MRI shows an abnormal region of the prostate suspicious for cancer (or a “target”) then we, ideally, should be doing a targeted or a fusion biopsy next, not a blind random or non-targeted biopsy.”
Dr. Scionti says the MRI-US Fusion-Guided Biopsy method trumps blind biopsies because it is more accurate, and with the proper anesthetic techniques, can be painless.
“The traditional method of using a transrectal ultrasound-guided biopsy that takes 12-14 needles is feared by many men,” Dr. Scionti says. “Not only it be painful, but it is also inaccurate up to 51 percent of the time and cannot accurately identify all the cancerous regions of the prostate gland.”
With MRI-US Fusion-Guided Biopsy, Dr. Scionti says the MRI images reflecting abnormalities are superimposed (or fused) onto a set of ultrasound images and the computerized system gives the urologist a biopsy pathway or guidepath to follow so that a precise biopsy is done in which abnormalities revealed by the MRI images, are targeted. Taking samples using computer technology throughout the prostate gives physicians a better understanding of where the tumor is and also becomes a roadmap to design a focal targeted treatment.
With this advanced technique, Dr. Scionti says physicians can precisely identify the size, location, aggressiveness, and stage of a prostate cancer.
“MRI-US Fusion-Guided Biopsy is the gold standard of how prostate biopsies should be done today,” Scionti said.
